Hello,

How could it be possible to create some custom fields as mentioned on the attachment.

Hi,

See this page:
demo.flexiblewebdesign.com/cleanmart/index.php/vm-product-details-page/product-details-flexv2-layout

and Look at the TABs at the bottom. You will see "Specification". With our Template. It is possible to create custom fields and put them inside the TAB.

To create the Specification TAB.
see this PDF file: flexiblewebdesign.com/media/tutorials/cleanmart.pdf

and look at the 12th page in the PDF. It has been explained in there.

If you want to move the "Specification" Tab and put those custom fields under product picture. I can't help on that, because it is a custom modification and our free support doesn't cover custom modification. You would need a premium support if you want us to take care this modification for you. You can purchase premium support from here:
